Xihai University’s postgraduate re-examination process has begun.
Every university attaches great importance to the admission of graduate students, because the admission of graduate students is directly related to the source of students for scientific research, and even to the future development of the school.
Wang Hao's graduate student recruitment work is a top priority, because students who apply for Wang Hao's graduate school, especially those who enter the re-examination, have extremely amazing written test scores.
Not only did these students have amazing written test scores, they also came from prestigious domestic schools.
Among them, students applying for the mathematics major are from Shuimu University, Donggang University, Xijing University of Science and Technology and Sudong University, not to mention a confirmed foreign student, a talented student from Amerikan Ivy League University and Stanford University.
When it comes to admissions to the School of Science at Suimu University and Capital University, it doesn't seem to be a big deal, but it's different when it comes to graduate admissions at Xihai University.
This is mainly because the sources of students in colleges and universities vary greatly.
Even if Xihai University recruits lecturers, it is difficult to recruit doctoral students from top universities such as Suimu University and Capital University. For graduate student recruitment, recruiting undergraduates from top universities is even more difficult than recruiting PhD students from top universities.
Most of the universities where undergraduate students choose to study for graduate school will choose universities that are at the same level as or better than their undergraduate students. Otherwise, it seems that there is little point in studying for graduate school.
In fact, it is very clear when you look at the job market. Most companies attach great importance to the first degree. Undergraduate students from top universities are even more popular than graduate students from ordinary universities.
This is mainly because many people believe that the first degree means differences in wisdom and ability to a certain extent. The college entrance examination is a very fair screening platform. The results of students who can be admitted to top universities are very valuable.
In comparison, graduate students are worse.
Graduate students can be admitted through hard work, but for undergraduates from top universities, hard work accounts for a much smaller proportion.
For example, Shuimu University and Capital University admit many provincial champions every year.
Being able to get the top spot in a province is definitely something that can only be achieved through hard work. Even if you work ten times harder, without enough brain support, it is simply impossible to get the top score in the college entrance examination in the province.
Not to mention, in the past many years, many of the students admitted to the two universities were competitive students.
Mathematics Olympiads are not something you can win just by training. You must first have enough talent.
In scientific research, talent is very important.
In many highly technical jobs, talent is more important than hard work.
Xihai University attaches great importance to Wang Hao's recruitment of graduate students, and they have organized an interview expert group in advance.
Interviews for graduate students in the field of mathematics must be conducted with professors from the School of Science. Luan Haiping, dean of the School of Science, and Zhou Qingyuan, professor of mathematics, naturally entered the interview review team.
Two others joined, including Zhu Jianrong, director of the Science and Technology Department, and Yan Jin, president of Xihai University.
It’s not surprising that Zhu Jianrong joined the interview review team. He often participates in graduate student interviews.
Yan Jin is just interested.
As a university president, he wanted to join the interview team, so naturally no one would object.
This lineup is quite gorgeous.
Wang Hao was speechless when he saw the list of interview judges and muttered, "Whatever interview committee you want, I can do it myself..."
This sentence is very correct.
No matter what other interview review members think, the final decision-maker is Wang Hao himself.
…
Interviews for graduate students in mathematics begin first.
The interview location was a small office in the graduate school. When the interview time was approaching, several students who were participating in the re-examination had already arrived.
There are two girls and three boys among them.
There were two students from Donggang University sitting together, and the others were sitting alone and not talking.
There is a girl with pigtails who is very eye-catching, not because she is pretty, but because she smiles at everyone, and she looks like an outgoing girl.
Her name is Hu Lidan, from Xijing University of Science and Technology.
When he found that everyone was silent, Hu Lidan was the first to ask, "Are you all prepared for the interview? I don't know what will happen to Professor Wang's interview. I regret it now. I can get in with this score."
Shuimu University."
A boy next to him, named Xu Jie, nodded and said, "I also regret it a bit. I have already applied for it and there is nothing I can do. I have been very nervous these days and have been preparing for a long time."
"What have you prepared?" Hu Lidan asked curiously.
Xu Jie said, "Messenne prime numbers, Artin's conjecture and Kakutani conjecture. I downloaded several papers by Professor Wang Hao and looked at them one by one. Although I couldn't understand most of them, I still understood the general proof process."
Xu Jie's preparation surprised everyone else.
Hu Lidan couldn't help but give a thumbs up, "I thought I was well prepared, but I didn't expect you to be even more prepared than me."
"What have you prepared?" Xu Jie asked.
The other three students also looked over.
"I just carefully reviewed the content related to differential equations, and also looked at the content of differential equations at the graduate level." Hu Lidan explained, "I don't know what questions Professor Wang Hao will ask, but I think that as long as you study in a graduate school,
As long as there is research in the direction, Professor Wang Hao is best at partial differential equations, which is also his initial research direction, so I think..."
"Bala bala~~"
Hu Lidan said a lot in succession, which basically meant that Professor Wang Hao was probably asking about the content of partial differential equations.
After hearing this, others immediately felt that it made sense.
Anyone who has studied Wang Hao's achievements will know that he is good at partial differential equations and number theory, but it is difficult for undergraduates to learn how to study number theory.
Then it may be very important to review the content related to differential equations.
Chen Mengmeng sat in the corner, listening to the conversation between the two people, just like her name, feeling a little dazed.
She...wasn't prepared for anything.
She was the top scorer in the college entrance examination in Northern Xinjiang Province four years ago. She applied for Wang Hao's graduate school purely because she felt it was no worse than studying at Shuimu University, and it was mainly 'close to home'.
Since it is no worse than studying at Shuimu University for graduate school and is closer to home, I naturally feel that it is very good.
So she signed up.
Chen Mengmeng did not make any preparations. She has been a talented academic since she was a child. She thought that as the former top scorer in the college entrance examination in Northern Xinjiang Province and an undergraduate at Shuimu University, she would have the opportunity to be directly admitted to the postgraduate school. She would be among the best even in the postgraduate entrance examination.
Among the small town exercisers, he is definitely outstanding.
How difficult can it be to take the postgraduate entrance examination?
This is Chen Mengmeng's simple thought, but now listening to other people's discussions, she has lost a little confidence and feels that she is indeed too arrogant.
yes!
How can Professor Wang Hao’s graduate students take the exam so well? You still need to prepare more for the re-examination!
…
Amid the chatter and apprehension of several students, the interview finally officially began.
The first interviewer was Xu Jie from Soochow University. When he entered, he saw five interviewing teachers.
Wang Hao, the youngest, sat on the edge.
The first person to ask a question was a little old man, "Please introduce yourself."
This is a normal question.
Xu Jie was well prepared for the interview. He immediately told what he had prepared and also talked about his practical experience in scientific research at the university.
The second questioner was Zhu Jianrong. He asked several questions in a row, "Are you planning to study for a Ph.D. after graduate school?"
"Why did you choose to take the postgraduate entrance examination instead of working directly? I see from your resume that you graduated from Sudong University, right? And your grades are quite good. It should be easy to find a good job."
"Do you have a definite career plan? For example, after completing your graduate studies at Xihai University, will you consider staying at the school to study for a Ph.D., and then continue to engage in research in the field of mathematics?"
Zhu Jianrong asked several questions in succession, all of which were expected.
The next questioner was Zhou Qingyuan. Zhou Qingyuan asked a professional question, "Let's talk about the solution of non-homogeneous partial differential equations. How many methods have you learned? Which equations can be solved?"
This question tests the students' mathematical level.
Xu Jie suddenly became a little nervous, and at the same time he admired Hu Lidan very much. He actually had a professional question about partial differential equations, but the person who asked him was not Wang Hao, but an unknown old professor.
His grades were still very good and he said something even though he was unprepared.
After Xu Jie finished everything, Zhou Qingyuan didn't know whether he was satisfied or dissatisfied, but just nodded lightly.
Luan Haiping's question was very direct, "Give me a reason to admit you."
Xu Jie breathed a sigh of relief and immediately spoke with confidence. He talked about the mathematical research work he had participated in during the four years of college, and expressed that he was very interested in mathematical research and hoped to devote his life to research on the basics of mathematics, etc.
.
This answer is still very standard.
After Luan Haiping asked questions, he stopped asking any more questions. Xu Jie walked out of the door with doubts, but he didn't tell anyone else and just sat back silently.
After all, they were competitors, so it was impossible for him to reveal the problem in advance, but he still gave Hu Lidan a thumbs up.
It was just a small movement, and only Hu Lidan noticed it, but she still understood what Xu Jie meant, and a confident smile suddenly appeared on her face.
Next, Zhang Haijiang.
Zhang Haijiang is a student at Donggang University. He was asked similar questions after entering.
His performance was somewhat inferior to Xu Jie's. He didn't even answer the question of partial differential equations. He was obviously a little disappointed after he came out, and his eyes were red after he returned to his position.
Next, Hu Lidan.
Hu Lidan won the ‘Knowledge’ question.
Zhou Qingyuan's research and development field is partial differential equations. The questions he asks each student are different, but they are still in the field of partial differential equations and do not exceed the level of undergraduate students.
Other people’s questions are all open-ended, and it’s hard to say whether they are good or bad.
The next one, Qiu Hui'an, is very mediocre.
The next one is Chen Mengmeng, her performance can be said to be the worst.
Although she was very good among the group of question-answers in the small town, because she didn't make much preparation for the re-examination, and she was very nervous when she went in, she could answer almost no questions in one go.
After all the individual interviews were completed, the interview review team also started discussing.
Zhou Qingyuan said, "I think the first few are very good, especially Hu Lidan, who is very good, and obviously the opponent is well prepared, although her university education is a bit poor..."
Xijing University of Science and Technology is not a bad school, but compared to other institutions where others graduated, it is indeed much worse.
Zhu Zhenrong admired Xu Jie very much, "Xu Jie from Soudong University is also very good. This student speaks very sincerely and looks very confident."
Yan Jin admires the "mediocre" Qiu Hui'an and Zhang Haijiang more. He believes that only those who are mediocre in interviews will have a future in research and development. Anyway, they have a cheerful personality and fluent interview answers. For mathematics research, they are basically negative.
Performance.
Where can any mathematician have a very cheerful personality?
Where are the mathematicians who are good at talking?
Finally, everyone else looked at Wang Hao, and Wang Hao said, "The interview is not over yet. I have a question that they need to do together."
"ah?"
Unknown to others, Wang Hao also prepared questions.
Then they saw Wang Hao walking to the door, calling the students to come in, and carefully assigned a few seats to them, and took out five test papers from the bag and distributed them one by one, "This question, for
You have half an hour."
"Whether you can do it or not is secondary, and even whether you can understand it is secondary, but I hope you can give me a way to solve the problem."
"If you say it well, it will definitely get high marks here."
"..."
Several interview judges were very surprised after hearing Wang Hao's words.
Zhou Qingyuan walked over and glanced at the question, then froze on the spot, with a strange expression and his mouth wide open in surprise.
"NS equation?"
Others also went over and took a glance, and immediately looked at Wang Hao with a strange expression, which basically meant, "Are you serious?"
Several students got the test papers and were eager to try.
It can be said that they are all outstanding among the small town's problem solvers. What they are best at is doing the test questions, but when they got the test paper, they were immediately confused by the questions above.
"NS equation?"
Xu Jie, Zhang Haijiang, and Hu Lidan had all heard of the NS equation and knew that this problem was one of the seven major mathematical conjectures of the millennium, and they knew that they would definitely not be able to solve it.
Their faces turned dark when they saw it.
NS equation?
If you can solve this kind of question, do you still need to take the postgraduate re-examination here...
They all felt like they were dreaming. Xu Jie pinched his face hard, as if to verify that they were not dreaming.
Chen Mengmeng and Qiu Hui'an have never heard of it at all.
They know the seven millennium mathematical conjectures, but they don’t know that the NS equation is one of them.
This is actually quite normal.
Some of the seven major mathematical conjectures of the millennium are very famous, but some are rarely known. The NS equation belongs to the latter. The main reason is that it is difficult to understand the NS equation and requires a sufficient foundation.
Knowledge may be forgotten at a glance.
Regardless of whether they know it or not, when they look at the questions on the test paper, their performance is the same. They cannot understand the questions at all.
Although Wang Hao gave a simple explanation above and tried to explain it in an understandable way, the content involved in NS is too complicated and cannot be understood by undergraduates.
Even the question can only be roughly understood, and it is impossible to answer it.
Xu Jie, Zhang Haijiang, and Hu Lidan simply gave up. They began to think carefully about what Wang Hao said and what they would say later.
Qiu Hui'an also couldn't understand the question, but he still tried to use his own knowledge to answer the question, but the content he wrote didn't even make sense to him.
Among them, only Chen Mengmeng was really thinking seriously.
Chen Mengmeng was in the same situation as Qiu Hui'an. She also knew little about the problem, and she also didn't know one of the Millennium Mathematics Conjectures, but she still seriously thought about the direction of solving the problem.
But obviously thinking about the direction of solving the problem is useless.
Chen Mengmeng was thinking blankly. When the time almost passed, he didn't think of anything.
time up!
Wang Hao asked everyone to put down their pens, then asked them all to go out, and then came back in one by one for the interview.
There were no other questions this time. Wang Hao just asked them to talk about their thinking about the topic just now.
By this time, the students have realized that the real interview begins now.
You also found the other interview reviews very interesting. You asked a few undergraduates to explain their opinions and suggestions on the NS direction...
What can be said?
The first one to come in was still Xu Jie. He had already thought about how to answer, "I was doing the questions very seriously just now, but this question feels completely beyond my ability."
"The NS equation is one of the seven major mathematical conjectures of the millennium. I believe no one can figure it out until now, including Professor Wang Hao, and neither can you."
Wang Hao nodded, "I am preparing to do this research."
Xu Jie continued, "I think that if you want to solve this problem, you must have a very rich knowledge. The basics are the most important. In the future, when you study for graduate school, you must learn the basics well in order to..."
"Wow wow wow~~"
He said a lot in succession.
Wang Hao was a little confused after hearing this. Why did this student educate me?
Several other people think that what Xu Jie said is right. Only by laying a solid foundation can we do research. It is indeed good to have this awareness!
After Xu Jie finally finished speaking, Wang Hao quickly let the next person in.
Hu Lidan.
Hu Lidan's answer was almost the same as Xu Jie's. The difference was that she said in a different direction, "I think this problem cannot be solved by using knowledge in the field of differential equations alone. Algebraic geometry and Riemannian geometry should also be involved."
"Do you know Riemannian geometry?" Zhou Qingyuan asked in surprise.
Hu Lidan's face turned red, "I just heard about it."
After Hu Lidan said a few more words, she went out and replaced the next one.
Next, Qiu Hui'an and Zhang Haijiang just said a few words according to their own understanding, but at least they did not use clichés, which made Wang Hao's senses slightly better.
Finally it was Chen Mengmeng’s turn.
When Chen Mengmeng was doing the questions, he spent the whole time thinking. As a result, he didn't think of anything and was very nervous when he walked in the door.
She stood in front of Wang Hao and didn't say anything for a long time. It took a long time before she said, "I think..."
"This...this..."
"I'm so sorry, Teacher Wang Hao, my knowledge level is not enough and it is impossible to solve this question."
"I just thought about it, I should start with the simple ones first, study them, and then consider this difficult problem after I am familiar with the simple problems, so that I can learn to solve it."
Chen Mengmeng's opening let others know that she didn't know the NS equation at all, and certainly didn't know that the NS equation was one of the seven major mathematical conjectures of the millennium.
Several other judges immediately shook their heads.
Wang Hao's eyes lit up because he received the system prompt——
[Task 1, inspiration value +1!]
very good!
He looked at Chen Mengmeng with great satisfaction, nodded and said, "I have admitted this student, and it is up to you to decide the rest."
"??"
The other four interview judges were stunned. In their opinion, Chen Mengmeng was the worst performer. Why was he admitted directly?
